It’s back to work for the Space Shuttle Discovery crew. After a day off, the crew will spend much of today getting ready for their undocking from the International Space Station.

The crew woke at 12:19 a.m. CDT with the Aggie War Hymn performed by the Fighting Texas Aggie Band. It was for Mission Specialist Mike Fossum, a graduate of Texas A&M University.

The first activity of the day will be media interviews for most of the crew -- shuttle Pilot Mark Kelly, Mission Specialists Fossum, Lisa Nowak, Stephanie Wilson and Piers Sellers, and station Expedition 13 Commander Pavel Vinogradov and Flight Engineer Jeff Williams. Beginning at 3:03 a.m. they will talk with journalists from CNN, ABC News, NBC’s Today Show, and CBS News.

Meanwhile, shuttle Commander Steve Lindsey and station Flight Engineer Thomas Reiter will deactivate the multipurpose logistics module Leonardo and begin preparing for its move back to Discovery’s payload bay. Nowak and Wilson will use the station robotic arm to maneuver Leonardo, which has been packed with more than 4,000 pounds of experiment results, unneeded supplies and equipment from the station, to its place in the cargo bay.

The two, joined by Lindsey, will also use the arm with the boom extension to conduct a scheduled final inspection of the shuttle’s port wing to ensure it has not been damaged by orbital debris during the docked operations.

Throughout the day, the remainder of the crew will continue with final transfer of supplies and equipment from the shuttle’s middeck, organize the spacewalk tools and do other tasks to get ready for Discovery's undocking from the station on Saturday.

The next STS-121 mission status report will be issued Friday evening, or earlier if events warrant.
